Massey 65 Coolant

Massey model 65 1964 Utility

Perkins A4.203 diesel

I've been reading about coolant as I have to replace my radiator.
Since the Perkins 203 is a dry sleeve engine I don't think I have to worry about anti cavitation additives.
But what about an electrolysis additive?
Are these engines prone to electrolysis or is that just the wet sleeve engines?

Then there's the heavy duty anti freezes.
The low silicate stuff. Regular stuff and super stuff, the supposed long lasting kind.
What about those?
Regular old green glycol Prestone?

Cooling systems on tractors are often ignored until the damage is done. My capacity is about 40 qts by the book and I intend to use distilled water for 1/2 of it for a 50/50 mix.
I'd like to get it right the first time for a lasting solution. The stuff is expensive, super stuff even more so.

Again, thanks for the help.

I've always used the plain, old, inexpensive green antifreeze. Never had any problems, besides like oil, and batteries not every company that sells their own brand of oil doesn't have their own refinery, nor do they all have their own plant to make their batteries. The same goes for antifreeze, and other items.

For older tractors I have found that an
ethylene glycol AF is more than adequate.
In the UK I nrmally use a 30% solution.
This is strong enough to cover our winter
temperatures with a margin. It is important
to keep diluted AF to top up and maintain
the strength. This AF is also a summer
coolant which helps to protect the engine.

Thanks, men.
Ethylene glycol it will be, the plain old green stuff and I'll add a rust inhibitor per the operator manual.

Turns out that electrolysis is not a problem of either of wet sleeve or dry sleeve engines. Its a problem of the electrical system caused by having inadequate grounds. Its tested by grounding multimeter to the battery ground and then inserting positive lead into the coolant avoiding the radiator neck. And it can be tested at various other points with loads on and off as desired by the operator, watching for current flow on the meter. If you get over .10v investigate your grounds further and don't ever use a radiator point as a ground.

I mistakenly thought it was due to dissimilar metals in contact with each other, but from reading it mainly affects aluminum parts. Learn something every day I reckon. The good thing about these old tractors is there just ain't much aluminum on them. They are pretty robust with a minimum of care.

The minimum stuff being regular oil and filter changes along with intake air maintenance, clean fuel and filters, and a properly operating cooling system along with good hydraulic fluid levels and it will last and run for a long time. I do love my old tractor.

Many thanks again for sharing your knowledge.

Thanks once again guys.
